Filebeat Is not Sending Logs to Logstash even Harvesting Successfull

Question

I am trying to use ELK space to collect file logs. Everything is OK untill filebeat integration. I can send the logs over tcp to logstash and see in the kibana. But I couldn't achieved filebeat setup to send the logs. It seams sending the data but can not see at elasticsearch.

Using this command to create elasticsearch.

docker run -d -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" --name elasticsearch docker.elastic.co/elasticsearch/elasticsearch:7.5.2

Kibana:

docker run -d -p 5601:5601 -h kibana --name kibana --link elasticsearch:elasticsearch docker.elastic.co/kibana/kibana:7.5.2

Logstash:

docker run -d -p 5044:5044 -p 5000:5000 -h logstash --name logstash --link elasticsearch:elasticsearch -v c:/elk2/config-dir:/config-dir docker.elastic.co/logstash/logstash:7.5.2 -f /config-dir/logstash.conf

Logstash.conf file

input {
    beats {
        type => "test"
        port => "5044"
    }
}

filter {
  #If log line contains tab character followed by 'at' then we will tag that entry as stacktrace
  if [message] =~ "\tat" {
    grok {
      match => ["message", "^(\tat)"]
      add_tag => ["stacktrace"]
    }
  }

}

output {

  stdout {
    codec => rubydebug
  }

  # Sending properly parsed log events to elasticsearch
  elasticsearch {
    hosts => ["elasticsearch:9200"]
  }
}

Running filebeat on windows 10 machine. Downloaded zip and filebeat.yml config

filebeat.modules:
filebeat.inputs:
- type: log
  enabled: true
  paths:
    - C:/elk2/filebeat/log/*.log
  multiline.pattern: '^[0-9]{4}-[0-9]{2}-[0-9]{2}'
  multiline.negate: true
  multiline.match: after

output:
  logstash:
    hosts: ["localhost:5044"]
#Also tried 127.0.0.1/logstash/ip... as hosts here

Running powershell as admin mode and first

./install-service-filebeat.ps1

then

./filebeat.exe -c ./filebeat.yml

But no result at elastic search.

Try removing inverted commas in the port

input {
    beats {
        type => "test"
        port => 5044
    }
}
